Title: Innovations of James Macarthur
Introduction
James Macarthur is an accomplished inventor based in Santa Clara, CA. He holds a total of 5 patents that showcase his expertise in programmable logic and memory design. His innovative contributions have significantly impacted the field of integrated circuits.
Latest Patents
One of his latest patents is titled "Configurable memory design for masked programmable logic." This invention involves a mask programmable integrated circuit that includes a read-only memory (ROM), a random access memory (RAM), and a controller. The controller is designed to sense a reset condition and directs either a clear of the RAM or a preload of contents from the ROM to the RAM. This preload can occur after a successful self-test of the RAM. The RAM is configurable with variable word lengths and depths, allowing it to operate in various modes. Additionally, the integrated circuit features two multiplexers (MUX) that selectively couple data to the RAM, enabling it to emulate different logic functions.
Another significant patent by Macarthur focuses on "Techniques and circuits for high yield improvements in programmable devices using redundant logic." This patent describes a programmable logic device that includes redundant sets of logic blocks, which can be enabled or disabled. The device is designed to ensure that good logic blocks are operational while nonfunctional blocks are powered off and bypassed in the programming software. This innovation enhances the efficiency and reliability of programmable logic devices.
